arch/x86_64: align the user stack pointer when entering user space
The task and pthread entry points were entered with the stack pointer
left by the kernel side of the startup path, not aligned to the 16
bytes the ABI requires: applications calling a variadic function with
floating point arguments crashed with a general protection exception
on the first SSE store of the argument save area. Align the stack
pointer when returning to user space, where the value is known.
